services which also means additional billing and a far more professional service . Our independent research and testing at several clients ( that is available to anyone to see ) has shown up to 97 % improvement of airflow efficiency over coils as measured before and after service . For large corporates , hospitals , malls , and so on – this can equate to millions of rands in energy savings each year , not to mention the direct result of healthier air for buildings by removing the dirt that houses mold , bacteria and other pathogens . Energy savings are all around us and we can start with the easiest rewards such as cleaning and maintenance ,” says Mike Blow , chief executive officer of O3 Chemicals .
The value of the system is further complimented by QR code traceability , real time technician monitoring and inputs via smart phone , and historical data being generated that can trigger maintenance schedules in future that advise each building unit on the required amount of chemicals needed precisely ( no guess work or wastage ). The process also ensures another aspect eliminated that leaves a bitter taste in facility owners / managers mouths – being the payment for cleaning and maintenance that never actually gets done .
The proof is in the pudding as they say , and according to Chris Davey , national technical manager of Old Mutual
Property , he says , “ We are able to confirm that we have been utilising O3 Chemicals in all our retail centres for a period in excess of seven years . The primary use of O3 is the cleaning of the air handling unit coils in our HVAC systems . We have found the products to be very effective , producing a clean and efficient result and we have made the use of O3 a mandatory requirement for all air conditioning service providers maintaining our equipment . The products assist in our sustainability drive reducing the amount of water required during the coil cleaning process as well as improving air flow and resultant thermal transfer capability of the coils .”
The use of the chemicals as part of this solution is 100 % environmentally friendly and any overflows into drip trays , condensate pipes and drains will clean whatever they touch . RACA
